The food chain is very important to ecosystems.
Acquired immunity is the type of immunity that exists when a person is exposed to an antigen and subsequently makes antibodies against the antigen.
Immunity is the defense mechanism of the nervous system to avoid pathogens affecting the body and making it sick. There are two major types of immunity: innate and acquired. Innate immunity is the kind of immunity present in the human body by birth. Whereas, acquired immunity is gained over time.
Acquired immunity specifically promotes the antibodies or lymphocytes to inhibit the action of pathogens when it encounters one. It is further categorized into two types: active and passive immunity.
Active immunity indulges in the primary response to a pathogen. It produces antibodies to fight against it and preserves some to fight against the same pathogen encountered for the second time. Passive immunity, in addition, involves the medications prescribed to enhance immunity.

The answer is benedict’s reagent. Benedict’s
test is used to detect reducing sugars in solution when heated. The color
change occurs from clear blue to a brick-red precipitate in the presence of the
reducing sugars. The cupric compounds in
the benedicts reagent react with the reducing sugars (enediols) produced from
heating of the reducing sugars in the presence of an alkali. Benedict's reagent is comprised of a mixture of sodium citrate, sodium carbonate, and
copper(II) sulfate pentahydrate.
